A Shell Device for Reactive Power Compensation

Abstract

The invention discloses a shell device for local reactive power compensation. The shell device comprises a box body and a roof cover, wherein the box body and the roof cover form a hollow chamber for containing a local reactive power compensation device; the front surface and the rear surface of the box body are provided with box doors; a heat dissipating mechanism is arranged on one side surface of the box body, two wire entrance holes for containing connecting wires of the local reactive power compensation device are formed in the other side surface of the box body in an up-down manner, a pair of parallel first guide rails and a movable plate for placing the local reactive power compensation device are arranged at the lower ends of the left inner side surface and the right inner side surface of the box body, and a layer of flexible plastics for reducing the vibration of the local reactive power compensation device is arranged on the movable plate. The shell device has the good noise reduction, heat dissipation, dust-proofing and insulating effects, can be used in outdoor occasions, damp ground occasions, and occasions with strong vibration, can well protect the local reactive power compensation device in the device and enables the local reactive power compensation device to normally run in a good environment.

Description

technical field [0001] The invention relates to the field of on-site reactive compensation, in particular to a shell device specially used for on-site reactive compensation. Background technique [0002] With the development of the country's economy and the improvement of people's living standards, a large number of residential buildings, high-end shopping malls, hotels, office buildings and other civil buildings have sprung up in cities, which has led to a rapid increase in urban electricity consumption. However, single-phase inductive loads are mostly used in these civil construction sites. Because of their low power factor, the proportion of lagging reactive power in the grid is relatively large. In order to ensure the reduction of reactive power in the grid, a capacitor reactive power compensation device is usually installed in the low-voltage power supply and distribution system. After installing reactive power compensation equipment such as shunt capacitors in the pow...
